Chemists are able to kill cancer cells by adding an adamantyl group to a drug that binds cancer-promoting proteins.
a) How does the large greasy adamantyl group effect the surface of the protein? What does it mimic?
b) What other proteins or cellular systems will respond to this “sign” on the protein surface?
a) adamantyl group act as a lipophilic bullets. It is interact with lipophilic zone of the surface protein.
b) it known that it bind to DNA and regulate P53 gene as well. It influence P53 indipendent apoptotic pathway by ROS singal.
please see this review The Lipophilic Bullet Hits the Targets: Medicinal Chemistry of Adamantane Derivatives.

Most cancer medications kill rapidly dividing cells, such as those in tumors. Two common side effects of cancer medications are hair loss and digestive tract upsets. Make a hypothesis about why these two side effects are seen in people taking cancer medications, and explain your reasoning. (Hint: The cells on your scalp and those that line your digestive tract are both part of surface tissues called epithelia. Your skin is also an epithelium. Have you ever noticed how you constantly...
After isolating and culturing breast cancer cells from a patient sample, you were able to identify a transmembrane protein that was highly upregulated and unique to the cancer cells. Your PI wants you to produce aptamers that will bind to this transmembrane protein so that you can later conjugate the aptamer with a drug. You have to look back at your BENG168 notes on how to create and select for aptamers. Sketch a simple schematic of the SELEX process. Your...
Question 1. You are a cancer researcher studying skin cancer cells that have become metastatic (ie. they've migrated from the site of the original tumor to establish new secondary tumors). You analyze skin samples from an unaffected patient and from one with the metastatic cancer. After a series of detergent solubilization and centrifugation steps, you separate pellet samples from each tissue type by gel electrophoresis and find the following results: skin normal cancer tissue tissue 250 Da 120kDa 75kDa- 60kDa...
Question 1.
You are a cancer researcher studying skin cancer cells that have
become metastatic (i.e. they’ve migrated from the site of the
original tumor to establish new secondary tumors). You analyze skin
samples from an unaffected patient and from one with the metastatic
cancer. After a series of detergent solublization and
centrifugation steps, you separate pellet samples from each tissue
type by gel electrophoresis and find the following results:
A. What is the difference between the normal skin sample...
2) Given that E6 inactivates p53-dependent pathways, cervical
cancer cells are particularly resistant to traditional treatments
such as chemotherapy, the search is ongoing for new alternative
therapeutics to be used in conjunction with current
chemotherapeutic drugs. One such candidate is the plant flavonoid
Luteolin. In 2014, Ham et al evaluate the effectiveness of Luteolin
on sensitizing cervical cancer cells to apoptosis.
a) In Figure 1, panel A, the researchers looked for an effect on
E6 levels post Luteolin treatment. What...
1. Gleevec is a drug that has transformed Leukemia treatment and cancer research. Gleevec is a form of therapy known as a TKI (tyrosine kinase inhibitor). Tyrosine kinase is an essential protein in cancer pathogenesis. Gleevec binds this protein and inactivates it. Hence it is able to cure treat certain cancers very effectively. Here is the chemical structure of Gleevec (not all hydrogens are shown): a) A dear family friend has contracted Leukemia. Gleevec has been proposed to be a...
explain 1 or 2 molecular details in how epigenetics may allow
melanoma cells to outsmart BRAF inhibitors
**This is for a genetics course
Seope: This science commentary claims that epigeneties plays a role in cancer cells becoming therapy-resistant. The language used is generalized for the non-scientist and does not include any molecular details, such as methylation of a specific nucleotide in an allele or modification of a specific histone tail amino acid. Your task (individually or in a group of...
Depletion of cholesterol in the cell membrane using a drug (mevastatin) has been associated with apoptosis in cancer cells. a. What effect would cholesterol depletion have on the integrity of lipid rafts in the membrane? b. Researchers found that FAS death receptor was activated in cholesterol depleted cancer cells. Explain how activation of this receptor activates killer caspases. c. When a caspase is converted from its inactive to its active form there are changes in the primary and tertiary structure...
in cell culture experiments...Does exogenous oxidized glutathione (GSSG) protect cancer cells? Is it converted to the reduced form GSH once it's taking up by the cell to protect the cell? i know that both of them is forming the other and the amount of formation of certain form depends on the status of the cell. i'm working on cancer cell lines and when i used both forms to see their effect on the cell survival, both of them shows cell...
Adaptive Immunity Worksheet in the body. a. What 1. Adaptive immune cells will interact mainly at the about this organ makes it a good place for the cells to interact? 2. The adaptive immune system is divided into two responses: The response, which uses B cells, and the response, which uses T cells. 3. What is one difference between antigen that B cells respond to vs. antigen that T cells respond to? 4. Fill in the following information about 3...
